A good compiler for a beginner is WINAVR.

Google for it.

Good beginner project, not to many things to get wrong.

You asked about this before.

You CAN NOT run a USB webcam with an 8535.
This is not a beginner project.

Get your sprinkler working first, same time next year you can look at another simple project.

don

I bought several books to learn to program my AT-MEGA8535 , but I need C 
compilator.
I'm going to use IAR but I'd like listening your suggestions with advantages 
and disadvantages.

What compilator can you suggest me ?

I wish to create 2 projects:

1. AUTOMATIC SPRINKLER TIME for my garden
2. webcam for register images, during 24h, on hard disk

I use WINAVR for commercial products, so I am sure it will work for you.

But since you have not tired it yet, I think you will need to decide for your self now.

Good luck on the webcam project, let us know how it works.

What many use is WInAVR (which works with gcc). IAR is pretty  
expensive though your sprinkler timer should be small enough to use  
the free version.

I am not even sure that you can do anything with a webcam and 8535  
except maybe turn it on and off.

Many use gcc/WinAVR for commercial development. None of the current  
notable limitations have ANY effect on your chosen controller. The  
significant limitations only effect controllers with (I think it is)  
more than 256K occupied code space.

I think if you "study" either one of them and therefore think it is too much bother to study the other some time in the future, that you haven't learned anything at all.

On email lists and forums we see this all the time with AVR users not even willing to consider a PIC or ARM. And vice versa. Is often so bad that 8535 users won't consider AT-Mega parts, never mind the less-than 10,000 quantity price of the the older 8535 is essentially the same as for more capable parts.

I seriously recommend that you revisit your CPU selection looking for an AVR with JTAG or Debug-wire interfaces for on-chip symbolic debugging. Strongly suggest that you study the AVR Dragon and specifically the CPUs that the Dragon supports. The Dragon costs roughly $50. The next step up is $300 and isn't really any better for CPUs that the Dragon supports.

1- AT-Mega8535 has JTAG or Debug-wire interfaces for on-chip symbolic debugging ?
I have AVR ISP programmer MKII + STK 500 board

2- I'm reading book which say to use CodeVisionAVR Standard compiler (HP InfoTech), what do you think ?

thanks

If you are willing to spend money on the IAR compiler, I would suggest you
invest in either the AVR Dragon or AVR JTAG ICE Mk2 at the same time. Which
one will depend on the processors you intend to use. 

 

This means you will want to drop the ATMega8353 and consider one of the
later devices with JTAG or debug wire capability. It will be well worth the
upgrade.

 

Using JTAG debugging will save you so much time in trying to figure out what
your code is doing, or not doing.  A friend of mine does all his programming
on the PIC in PICBASIC and no JTAG or ICE and spends about 2-3 times longer
than if he had some kind of in circuit debugger. He has to toggle port pins
in parts of the code just to see if he is reaching that point. With JTAG you
won't have that worry. Believe me, it is well worth the additional cost if
you really want  get into this properly.

I wouldn't have said "revisit your CPU selection" had the 8535 either of the debugging interfaces. You need to learn how to find this sort of thing for yourself: http://www.atmel.com:80/dyn/products/tools_card.asp?tool_id=3891

I think if it is important to you to be able to type examples from the book verbatim into your keyboard then continue with that book and CodeVision. However if the book uses AVR Studio it is very likely you can not get that exact version anymore.

I have been very pleased with WinAVR, even back in the days when it wasn't properly integrated into AVR Studio. Then again, I like Makefiles and do not like undocumented mysterious binary config files which can only be manipulated with a specific version of a GUI application. I hate having to search every corner of a drop-down menu or tab of a dialog box hunting for options and current settings.

Ok, I will drop my old 8535 but what to choose as processor ?
M164p, M324p, M644p or M1284p ?

Can you suggest me a good on line shop  fot buying AVR porogrammer ?
AVR Dragon or AVR JTAG ICE Mk2 ?

Depending on your code size, I would start with a 324. Then upgrade to  
644 if you need. I think availability of 1284 is a bit marginal still  
as it is relatively new.

1 -If you should give suggestion for your experience, what compiler should 
you choose ?
I think it's important good support, for example in IAR I noted it's 
necessary to select many options for specific processor in drop-down menu.
2- Do you know what compiler has major support in network ?

thanks

I would choose gcc, either through WinAVR or Eclipse. Eclipse runs on  
linux, Windows, Mac.

Any compiler will have a drop-down menu with many processor choices.  
After all there are many AVRs. And, there are no one-processor  
compilers. So, every one MUST do many. A long selector menu is no  
problem because you usually make that choice only once when you start  
a new project. Maybe you change if you shift to a larger processor.  
So, once, maybe twice, rarely three times in an entire project. Not a  
big issue.
